| dc.description.abstract | Tunnel magnetoresistance ratios of up to 40% ar
e measured between 10 K and 300 K when the highly
spin-polarized compensated ferrimagnet, Mn
2
Ru
x
Ga, is integrated into MgO-based perpendicular
magnetic tunnel junctions. Temperature and bias depen
dences of the tunnel magnetoresistance effect,
with a sign change near
0.2 V, reflect the structure of the Mn
2
Ru
x
Ga interface density of states.
Despite magnetic moment vanishing at a
compensation temperature of 200 K for
x
0
:
8, the tunnel
magnetoresistance ratio remains non-zero throughout the compensation region, demonstrating that the
spin-transport is governed by one of the Mn sub-la
ttices only. Broad temperature range magnetic field
immunity of at least 0.5 T is demonstrated in the sa
me sample. The high spin polarization and perpen-
dicular magnetic anisotropy make Mn

Ga suitable for applications
in both non-volatile magnetic
random access memory cells and terahertz spin-transfer oscillators | en |
