The Biaxial Strain Dependence of Magnetic Order in Spin Frustrated Mn3NiN Thin Films

Popis výsledku v původním jazyce

Multicomponent magnetic phase diagrams are a key property of functional materials for a variety of uses, such as manipulation of magnetization for energy efficient memory, data storage, and cooling applications. Strong spin-lattice coupling extends this functionality further by allowing electric-field-control of magnetization via strain coupling with a piezoelectric. Here this work explores the magnetic phase diagram of piezomagnetic Mn3NiN thin films, with a frustrated noncollinear antiferromagnetic (AFM) structure, as a function of the growth induced biaxial strain. Under compressive strain, the films support a canted AFM state with large coercivity of the transverse anomalous Hall resistivity, rho(xy), at low temperature, that transforms at a well-defined Neel transition temperature (T-N) into a soft ferrimagnetic-like (FIM) state at high temperatures. In stark contrast, under tensile strain, the low temperature canted AFM phase transitions to a state where rho(xy) is an order of magnitude smaller and therefore consistent with a low magnetization phase. Neutron scattering confirms that the high temperature FIM-like phase of compressively strained films is magnetically ordered and the transition at T-N is first-order. The results open the field toward future exploration of electric-field-driven piezospintronic and thin film caloric cooling applications in both Mn3NiN itself and the broader Mn(3)AN family.
