Post deposition interfacial Néel temperature tuning in magnetoelectric B:Cr2O3
Ather Mahmood, Jamie Weaver, Syed Qamar Abbas Shah +4
Boron (B) alloying transforms the magnetoelectric antiferromagnet Cr2O3 into a multifunctional single-phase material which enables electric field driven π/2 rotation of the Néel ve…
Search for magnetoelectric monopole response in CrO powder
Syed Q. A. Shah, Ather Mahmood, Arun Parthasarathy +1
Powder samples have been suggested as a pathway to fabricate isotropic magnetoelectric (ME) materials which effectively only have a pseudoscalar or monopole ME response. We demonst…
Nanoscale imaging of antiferromagnetic domains in epitaxial films of Cr2O3 via scanning diamond magnetic probe microscopy
Adam Erickson, Syed Qamar Abbas Shah, Ather Mahmood +4
We report direct imaging of boundary magnetization associated with antiferromagnetic domains in magnetoelectric epitaxial Cr2O3 thin films using diamond nitrogen vacancy microscopy…
Dynamic axion field in the magnetoelectric antiferromagnet chromia
Junlei Wang, Chao Lei, Allan H Macdonald +1
Chromia is a magnetoelectric insulator whose bulk magnetoelectric susceptibility contains a non-zero pseudoscalar component, like that present in magnetized topological insulators.…
Electromagnon excitation in cupric oxide measured by Fabry-Pérot enhanced terahertz Mueller matrix ellipsometry
Sean Knight, Dharmalingam Prabhakaran, Christian Binek +1
Here we present the use of Fabry-Pérot enhanced terahertz (THz) Mueller matrix ellipsometry to measure an electromagnon excitation in monoclinic cupric oxide (CuO). As a magnetical…
Robust isothermal electric switching of interface magnetization: A route to voltage-controlled spintronics
Xi He, Yi Wang, Ning Wu +5
Roughness-insensitive and electrically controllable magnetization at the (0001) surface of antiferromagnetic chromia is observed using magnetometry and spin-resolved photoemission…
Cole-Cole analysis of the superspin glass system Co80Fe20/Al2O3
O. Petracic, S. Sahoo, Ch. Binek +4
Ac susceptibility measurements were performed on discontinuous magnetic multilayers [Co80Fe20(t)/Al2O3(3nm)]x10, t = 0.9 and 1.0nm, by Superconducting Quantum Interference Device (…
Two-dimensional behavior of the sublattice magnetization in three-dimensional Ising antiferromagnets
O. Petracic, Ch. Binek, W. Kleemann
A three-dimensional layered Ising-Antiferromagnet with a ferromagnetic intra-layer coupling to z neighbors, zJ > 0, and an antiferromagnetic interlayer coupling to z' neighbors, z'…
Density of Zeros on the Lee-Yang circle obtained from magnetization data of a two-dimensional Ising ferromagnet
Ch. Binek
In order to provide an experimental access to the statistical theory of Lee and Yang (1952) the density function g(theta) of zeros on the Lee-Yang circle has been determined for th…
Field-induced transverse spin ordering in FeBr2
O. Petracic, Ch. Binek, W. Kleemann
Weak first-order phase transitions from axial to oblique spin ordering in FeBr2 are evidenced by SQUID magnetometry in axial fields H1(T) above the multicritical point, Hm = 2.4 MA…
