Field-induced magnetic phase transitions and metastable states in Tb3Ni

Magnetic glassy behaviour coupled with long range non-collinear magnetic order in Tb3Co

“…Fit to the above equation can be better done by plotting ln τ versus ln(T f − T 0 )/T 0 [3,25] as shown in figure 12. The slope of the linear fit yields a value for zν = 6.3 (2), which lies within the expected range of 5-10 for the different spin glass systems [26]. The value of T 0 is 70.9(1) K and τ 0 turns out to be 2.6 × 10 −17 s some what lower than the expected value.…”

“…A good refinement is obtained with R-factors R p = 6.4%, R wp = 8.1%, R exp = 6.4%, R B = 8.1% and Mag −R B = 8.9% and the refined pattern at 2 K is shown in figure 5. The magnetic moments obtained are µ x = −3.6 (2) µ B , µ y = 0 and µ z = 9.5(3) µ B for Tb at 4c site and µ x = 3.2(2) µ B , µ y = 3.83(2) µ B and µ z = 9.5(3) µ B for Tb at 8d site. No discernible magnetic moment was found on the transition element, Co, in this compound.…”

“…Rare earth intermetallic compounds have attracted physicists for their various interesting properties, such as wide variety of magnetic phenomena, a number of magnetic transitions as a function of temperature, complex magnetic structures, field driven magneto-structural transitions, giant magnetocaloric effect (GMCE) and so on [1][2][3]. One such family of compounds are rare earth rich binary compounds of R 3 T (R = rare earth, T = transition metal) type [4,5].…”

Na$_5$Co$_{15.5}$Te$_6$O$_{36}$: an $S$ = 1/2 stacked Ising kagome antiferromagnet with a partially disordered ground state

“…In some intermetallic alloys [48][49][50][51], the system has a AFM ground state and undergoes a field-induced AFM-FM transition. As the field is released, the kinetics of the FM-AFM transition is hindered with a fraction of frozen FM regime.…”
