Multiple magnetic phase transitions with different universality classes in bilayer La[Formula: see text] Sr[Formula: see text] Mn[Formula: see text] O[Formula: see text] manganite

Here, we report three magnetic transitions at 101 K (T[Formula: see text] ), 246 K (T[Formula: see text] ) and 295 K (T[Formula: see text] ) in bilayer La[Formula: see text] Sr[Formula: see text] Mn[Formula: see text] O[Formula: see text] . The second order phase transitions have been identified at...

description Here, we report three magnetic transitions at 101 K (T[Formula: see text] ), 246 K (T[Formula: see text] ) and 295 K (T[Formula: see text] ) in bilayer La[Formula: see text] Sr[Formula: see text] Mn[Formula: see text] O[Formula: see text] . The second order phase transitions have been identified at these transition points with the help of change in entropy analysis and modified Arrott plots (MAPs). The critical behavior around T[Formula: see text] , T[Formula: see text] and T[Formula: see text] have been studied by MAPs and Kouvel–Fisher method. Based on these analyses four magnetic phases are: (1) 2D Ising ferromagnetic (FM) below T[Formula: see text] ,(2) 2D Heisenberg canted antiferromagnetic (CAFM-I) and FM clusters in temperature range T[Formula: see text] < T < T[Formula: see text] , (3) 2D Heisenberg CAFM-II and FM clusters with non magnetically interacting planes in temperature range T[Formula: see text] < T < T[Formula: see text] and (4) paramagnetic for T > T[Formula: see text] .
