To date the realization of magnetoresistive random access memory (RAM) and magnetoelectric RAM (MeRAM) devices relies primarily on ultrathin ferromagnetic-based (FeCoB/MgO) magnetic tunnel junctions. On the other hand, the Heusler family of intermetallics is considered very promising for spintronic applications. Nevertheless, the voltage controlled magnetic anisotropy (VCMA) in ultrathin Heusler-based magnetic-tunnel junction stacks remains unexplored. Here, using the ferrimagnetic Heusler ${mathrm{Mn}}_{3}mathrm{Ga}$ as a prototype system, we report ab initio calculations of the electric field modulation of magnetism in the $mathrm{Ir}/{mathrm{Mn}}_{3}mathrm{Ga}$/MgO heterostructure. The trilayer structures with one and three monolayer Ir caps and Mn-Mn termination exhibit large perpendicular magnetic anisotropy in contrast to those with Mn-Ga termination which yield in-plane magnetization orientation. We predict giant VCMA coefficients the magnitude and sign of which depend on both the interface termination and the Ir cap thickness. The underlying atomistic mechanism lies on the electric-field-induced shifts of the spin-orbit coupling energies of the spin-polarized $mathrm{Ir}/d$ orbitals with different orbital angular momentum symmetries. Our paper paves the way for exploiting the unique magnetic properties of ferrimagnetic Heusler compounds for next generation MeRAM devices.

Metal-organic frameworks based on metal-formates have emerged as a intriguing class of multiferroics with wide range of applications. In this work, we present magneto-Raman spectroscopic investigations on [(CH3)2NH2]Co(HCOO)3 belonging to this family. The spectroscopic studies were performed at magnetic fields up to 31 T at the temperature of 2.3 K. It was observed that the formate bending mode at around 798 cm−1 shifts to higher energies with increasing magnetic field. The magneto-response of the phonon also exhibits anomalies at magnetic fields of 14.5 T and 23.5 T corresponding to magnetic phase transitions. Based on our results, we conclude that the formate bending mode does play a role in facilitating the saturation of magnetic states similar to its Mn and Ni analogs.

A conventional resonant detector is often subject to a trade-off between bandwidth and peak sensitivity that can be traced back to quantum Cramer-Rao Bound. Anomalous dispersion has been shown to improve it by signal amplification and is thus more robust against decoherence, while it leads to instabilities. We propose a stable quantum amplifier applicable to linear systems operating at the fundamental detection limits, enabled by two-mode non-degenerate parametric amplification. At threshold, one mode of the amplifier forms a PT-symmetric system of original detector mode. Sensitivity improvements are shown for laser-interferometric gravitational-wave detectors and microwave cavity axion detectors.
