Quasi-static magnetization dynamics in a compensated ferrimagnetic half-metal -- MnRuGa
Ajay Jha, Simon Lenne, Gwenael Atcheson +3
Exploring anisotropy and diverse magnetization dynamics in specimens with vanishing magnetic moments presents a significant challenge using traditional magnetometry, as the low res…
RuMnAl thin films
K. E. Siewierska, H. Kurt, B. Shortall +7
The cubic Heusler alloy RuMnAl is grown in thin film form on MgO and MgAlO substrates. It is a highly spin-polarised ferrimagnetic metal, with weak magnetoc…
Deterministic multi-level spin orbit torque switching using He+ microscopy patterning
Jinu Kurian, Aleena Joseph, Salia Cherifi-Hertel +7
He ion irradiation is used to pattern multiple areas of Pt/Co/W films with different irradiation doses in Hall bars. The resulting perpendicular magnetic anisotropy landscape e…
Single-pulse all-optical switching in amorphous DyCo and TbCo
Zexiang Hu, Jean Besbas, Ross Smith +5
Repeated uniform switching of the magnetization of thin films of ferrimagnetic amorphous Gd(FeCo) in response to single fast laser pulses is well established. Here we…
Magnetic reversal and pinning in a perpendicular zero moment half-metal
Niclas Teichert, Gwenael Atcheson, Katarzyna Siewierska +6
Compensated ferrimagnets are promising materials for fast spintronic applications based on domain wall motion as they combine the favourable properties of ferromagnets and antiferr…
Ultra-fast Double Pulse All-Optical Re-switching of a Ferrimagnet
C. Banerjee, K. Rode, G. Atcheson +4
All-optical re-switching has been investigated in the half-metallic Heusler ferrimagnet Mn2Ru0.9Ga, where Mn atoms occupy two inequivalent sites in the XA-type structure. The effec…
Magnetic order and magneto-transport in half-metallic ferrimagnetic MnRuGa thin films
K. E. Siewierska, G. Atcheson, A. Jha +8
The ruthenium content of half-metallic MnRuGa thin films, with a biaxially-strained inverse Heusler structure, controls the ferrimagnetism that determines their magnetic an…
Helium Ion Microscopy for Reduced Spin Orbit Torque Switching Currents
Peter Dunne, Ciaran Fowley, Gregor Hlawacek +11
Spin orbit torque driven switching is a favourable way to manipulate nanoscale magnetic objects for both memory and wireless communication devices. The critical current required to…
Sub-picosecond exchange-relaxation in the compensated ferrimagnet MnRuGa
G. Bonfiglio, K. Rode, G. Y. P. Atcheson +5
We study the demagnetization dynamics of the fully compensated half-metallic ferrimagnet MnRuGa. While the two antiferromagnetically coupled sublattices are both composed o…
Magnetization dynamics of the compensated ferrimagnet
G. Bonfiglio, K. Rode, K. Siewerska +7
Here we study both static and time-resolved dynamic magnetic properties of the compensated ferrimagnet from room temperature down to 10K, thus crossing the magnetic compensation te…
Single pulse all-optical toggle switching of magnetization without Gd: The example of Mn2RuxGa
C. Banerjee, N. Teichert, K. Siewierska +6
Energy-efficient control of magnetization without the help of a magnetic field is a key goal of spintronics. Purely heat-induced single-pulse all-optical toggle switching has been…
Giant spin-orbit torque in a single ferrimagnetic metal layer
Simon Lenne, Yong-Chang Lau, Ajay Jha +6
Antiferromagnets and compensated ferrimagnets offer opportunities to investigate spin dynamics in the 'terahertz gap' because their resonance modes lie in the 0.3 THz to 3 THz rang…
Study of the Effect of Annealing on the Properties of Mn2RuxGa Thin Films
K. E. Siewierska, G. Atcheson, K. Borisov +3
The effect of vacuum annealing thin films of the compensated ferrimagnetic half-metal Mn2RuxGa at temperatures from 250 to 400 degree Celsius is investigated. The 39.3 nm films dep…
Exchange coupling of a perpendicular ferromagnet to a half-metallic compensated ferrimagnet via a thin hafnium interlayer
Kiril Borisov, Gwenaël Atcheson, Gavin D'Arcy +3
A thin Hafnium film is shown to act both as an effective diffusion barrier for manganese at a thickness of 0.7 nm, and as an effective exchange coupling layer in a sandwich structu…
