In-plane magnetization

Fig. 2.34. Temperature dependence of the in-plane magnetic penetration depth extracted from (a) ac-susceptibility and (b) dc-magnetization measurements. The inset in (b) shows the low-T data in enlarged scale together with model curves for BCS (solid line) and for two triplet states, ti and t4 (broken curves). From [220] and [227]...

Recent esr measurements of low-spin Fe111 porphyrins at liquid helium temperature show sizable in-plane magnetic anistropy produced by the porphyrin skeleton (gi=2.9, g2 =2.3, = 1.5) and the contact... 

The results are shown in Fig. 2.9, where micrographs (a) and (b) respectively show thickness contours and in-plane magnetic lines of force. 

Fig. 5.17 Left part energy dependence of the photoelectron spectra analogously obtained to Fig. 5.16. The islands were created by heating an epitaxial cobalt film to about 1,000 K. From [55], used with permission. Right part for comparison, a fully relativistically calculated band structure for hcp(OOOl) bulk cobalt with in-plane magnetization is displayed. This calculation takes into account both spin-orbit interaction and exchange splitting on the same level of accuracy. The circles in the initial states show two regions where hybridization effects arc present. Reprinted from [28], Copyright (1998), with permission from Elsevier...

The influence of in-plane magnetic field (Hu) for Co thickness 1.30 nm covered with small amount of vanadium to reduce in-plane anisotropy field is shown in Fig. 3. Hh=1000 Oe (applied along X axis) is sufficient to produce irreversible changes in the domain structure. The period reduces from 3 pm (Fig. 3a) to 0.7 pm (Fig. 3b). Further return of Hu to zero has no influence on the domain structure. Despite of strong effect on domain period, HN does not induce...

The ME interactions at microwave frequencies for the spin-spray derived multiferroic heterostructures were demonstrated by an electrostatic induced in-plane magnetic anisotropy field Hts which resulted in large changes in the FMR field at X-band (9.5 GHz). Depending upon whether the HtB is parallel or perpendicular to the applied external magnetic field, the FMR field could be tuned up or down by electric field. The in-plane FMR fi equency can be expressed by Kittel equation ...
