Continuous tunable lateral magnetic anisotropy in La0.67Ca0.33MnO3/SrRuO3 superlattices by stacking period-modulation

AIP Advances, 2021
Effective control of magnetic anisotropy is important for developing spintronic devices. In this work, we performed a case study of stacking periods (N)-mediated reorientation of lateral magnetic anisotropy in ultrathin La0.67Ca0.33MnO3/SrRuO3 ...

Perturbative calculations of quantum spin tunneling in effective spin systems with a transversal magnetic field and transversal anisotropy

New Journal of Physics, 2017
We present a perturbative approach for the resonant tunnel splittings of an arbitrary effective single spin system. The Hamiltonian of such a system contains a uniaxial anisotropy, a transversal magnetic field and a second-order transversal anisotropy ...

Variation of magnetic easy direction of bcc structured ferromagnetic films up to thirty spin layers

Ceylon Journal of Science, 2017
Third order Heisenberg Hamiltonian was employed to determine the effect of number of spin layers on magnetic easy direction. 3-D graph of energy versus stress induced anisotropy and angle was plotted to find magnetic easy and hard directions.
