K magnetic susceptibility

Rhenium metal exhibits a very low paramagnetism which is field-independent and almost temperature-independent. In the range 79—471 K, magnetic susceptibility data for two independent samples were shown to correspond, when Tis in Kelvin, to the following equations (5) ... 

From fits of the high temperature (150 K < T < 250 K) magnetic susceptibilities of RAIB14 (Tb, Dy, Ho, Er), relatively large Curie-Weiss temperatures of 0 10 K were determined by Korsukova et al. (1989). However, the existence of magnetic transitions were not reported. An anomaly is that the Tb phase is reported to have 0 = 10 K, which indicates ferromagnetic interaction.

HojFcjSij crystallizes with the SCjFCjSij-type of structure P4/mnc, a = 10.39(1), c = 5.44(1) (X-ray powder analysis, Braun, 1980). Ho2FejSi5 orders antiferromagnet-ically at = 2.9 K. Magnetic susceptibility data = 10.4(1) jUg and = 0.3(7)] as well as Mossbauer spectra indicate the absence of a magnetic moment at the iron site (Braun et al., 1981). For sample preparation, see Dy2FejSi5. For low temperature heat capacity data, see Vining and Shelton (1983), = 2.82 K. Yarovets (1978)...

Resistivity, magnetic susceptibility, specific heat and inelastic neutron scattering were mea-siued for Cea Aus Sb4 by Kasaya et al. (1994). The compound was found to be a semiconductor with a resistivity of 22 cm at 0.13 K. Magnetic susceptibility and inelastic neutron scatter-... 

Equation (A2.5.20) is the Curie-Weiss law, and the temperature at which the magnetic susceptibility becomes infinite, is the Curie temperature. Below this temperature the substance shows spontaneous magnetization and is ferromagnetic. Nonnally the Curie temperature lies between 1 and 10 K. However, typical ferromagnetic materials like iron have very much larger values for quantum-mechanical reasons that will not be pursued here. 

A third exponent y, usually called the susceptibility exponent from its application to the magnetic susceptibility x in magnetic systems, governs what m pure-fluid systems is the isothennal compressibility k, and what in mixtures is the osmotic compressibility, and detennines how fast these quantities diverge as the critical point is approached (i.e. as > 1). 

The magnetic susceptibility of Na[Pu02(CH3COO)3] was measured by Dawson between 90 and 333 K (3). The resulting magnetic moment, yjff = 8.0 Ug, is temperature independent and corresponds to = 8.70 Ug, which is calculated from EPR measurements on a... 

Magnetic measurements of PuFi, between 4.2 and 300 K are consistent at high temperatures with older measurements (10-12). The large temperature dependent diamagnetism observed earlier was not found. Up to 100 K the susceptibility is nearly temperature independent with a value of X ip 2940 x 10-6 emu. The Curie-Weiss behavior near room temperature indicates population of a higher first excited state. The structure of PuFi, is isomorphic with that of UFi, (13), where two different sets of actinide atoms are 8-fold coordinated by a distorted antiprism.

With respect to the physical properties mentioned, band-structure calculations have attracted considerable interest, e.g., for SbSBr, SbSI, and SbSel (234). For the compounds having reference 22i in column 4 of Table XXIX, a temperature-independent diamagnetism has been found, with values of about 10 cm" g between 77 and 340 K. A small temperature-dependence is exhibited by BiTel, a narrow-gap semiconductor (41). The anisotropy of the magnetic susceptibility has been studied for SbSI, BiSel, and BiTel (41, 420). 

EuIn2P2 magnetic susceptibility shows a clear magnetic transition at about 24 K. In Fig. 11.5 c, magnetic susceptibility as a function of the a, a-h, and c direction were obtained on a plate crystal. The a axis exhibits the largest susceptibility and is the easy magnetization direction. The c axis is the hard magnetization direction. 

Magnetic studies show that the above compound is paramagnetic in nature in the temperature range 5-300 K. The magnetic susceptibility (xm) along with (Xm) vs T plots (1 Tesla) obtained from a DC-magnetization study of the powdered...
