Magnetic transitions and butterfly-shaped hysteresis of Sm-Fe-Al-based perovskite-type orthoferrite

Influence of the Magnetic Sub-Lattices in the Double Perovskite Compound LaCaNiReO$_6$

“…Because magnetisation saturation is never reached for ferrimagnets, we consider the remanent magnetization and calculate an effective magnetic moment of µ ef f 5K = 0.36µ B /f.u which is in agreement to results shown in [6]. In the 5K hysteresis loop, shoulders appears at zero field which indicate spin reorientation [18,19]. In the recorded loops at 75K and above these shoulders disappear while the remanence and coercivity decrease to a soft hysteresis loop at 105K.…”

Manganese substitution induced magnetic transformation and magnetoelectricity in SrFe12O19

“…The M – H plots of SrM5 and SrM7 are reminiscent of an FM loop squeezed in the middle (near H = 0) forming a “bee waist” like loop. This is an indication of the co-existence of two magnetic ordering, 48,49 although both are ferrimagnetic. This suggests the growth of another ferrimagnetic phase (FiM2) on substituting Mn at the Fe-site and interestingly this phase was found to be temperature dependent.…”

Physical Properties of PVDF-GO/Black-TiO2 Nanofibers and its Photocatalytic Degradation of Methylene Blue and Malachite Green Dyes

“…While the nano-black TiO2 (NB) displays the least average crystallite size, its lattice constants and unit cell volume relatively expand. Therefore, the NB density shows the minimum value of all samples [29]. Fig.…”
