Vibrating-sample magnetometer

Measurements. Infra-red spectra for the region 600-4000 cm-1 were measured with a Perkin-Elmer Model 710B spectrometer on samples pressed in KBr pellets. Magnetic susceptibilities were measured with a vibrating sample magnetometer (Princeton Applied Physics) as previously described.(4)... 

The magnetic susceptibility, measured with a vibrating sample magnetometer (Foner), calibrated with nickel (purity 99.99% — specific susceptibility at 293°K 55 cgs/g) at 293 0.2°K with a magnetic field of 17,700 G, is 101.39 0.20 10"6 cgs/g. This value may be compared with 101.65 0.20 10 6 cgs/g for manganese diphosphate prepared by thermal decomposition of the ammonium manganese phosphate. The value calculated from Reference 7 is 101.96 0.20 cgs/g. 

Here, Ms is the saturation magnetisation. Notice, that apparently, the stress transfer from the kapton substrate to the deposited film was ignored (compare eq. (IS) with eq. (1 Id)). A consistent result was obtained by determining the anisotropy from the hysteresis loops measured in the hard and easy magnetisation directions, using a vibrating sample magnetometer. 

The magnetization measurements have been carried out using an apparatus for magnetic measurements, constructed on the principle of a vibrating-sample magnetometer in the temperature range of 300-700 K in permanent magnetic fields up to 12 kOe under gas pressure up to 12 atm. 

Magnetic measurements were performed at temperatures between 2 and 300 K., in a vibrating sample magnetometer using a physical property measurement system (quantum design). 

Magnetic measurements were carried out on XeCPtE X. using a Vibrating Sample Magnetometer and those on all other materials were made using a SQUID magnetometer as previously outlined [12],... 

Magnetic measurements were made, with a 0.2265 g sample, over the temperature range 5 to 98.5 K using a Princeton Applied Research Corporation vibrating sample magnetometer. The magnetic standard was HgCo(NCS)4. 

Powdered samples, encapsulated in plug-capped Kel-F containers were studied using a vibrating sample magnetometer (Princeton Applied Research Corp.). Measurements were made in the range 4.2 -100 K and Hg(Co(SCN)4)2 was used as a standard [10]. The results for CgOsFg and CglrFg, are com-...
