Temperature-dependent periodicity halving of the in-plane angular magnetoresistance in La_0.67Sr_0.33MnO₃ thin films on LaAlO₃

Strain-engineering is used as a tool to alter electronic and magnetic properties like anisotropy energy. This study reports the different angle-dependent magnetoresistance of strain-engineered La0.67Sr0.33MnO3 (LSMO) thin films, grown on LaAlO3, compared their bulk analogs. Upon increasing temperature, symmetry change from fourfold [cos(4θ)] twofold [cos(2θ)] observed in resistance measurements. systematic with temperature allows us define three distinct temperature-dependent phases. The symmetric signal originates magnetocrystalline anisotropy, whereas believed be conventional anisotropic magnetoresistance. Our observations show that strain-engineering creates possibility manipulate which, for example, can ultimately lead noncollinear quasi-particles skyrmions single layer films LSMO.
