Nodal-Surface and Flat-Band Driven Large Anomalous Nernst Effect in Epitaxial Ferromagnetic Weyl Metal Fe5Si3
Shubhashish Pati, Sonali Srotaswini Pradhan, Nanhe Kumar Gupta +7
Magnetic topological materials such as Weyl and Dirac magnets exhibit unconventional electronic properties arising from the interplay between magnetic order and band topology, lead…
Emergent Anomalous and Topological Hall Responses in an Epitaxial Ferromagnetic Weyl Nodal-Line metal Fe5Si3
Shubhashish Pati, Sonali Srotaswini Pradhan, Abhay Pandey +9
The interplay between real and reciprocal space topology yields intrinsically linked transport phenomena in magnetic Weyl systems, wherein the broken time-reversal symmetry, strong…
Tailoring magnetic properties of CoFeB films via tungsten buffer and capping layers
L. Saravanan, Nanhe Kumar Gupta, Carlos Garcia +1
Controlling the interface between W and CoFeB-based buffer or capping layers at an appropriate temperature is essential for modifying the strength of magnetic anisotropy. In this w…
Effects of Interfacial Oxygen Diffusion on the Magnetic Properties and Thermal Stability of Pd/CoFeB/Pd/Ta Heterostructure
Saravanan Lakshmanan, Cristian Romanque, Mario Mery +3
We investigated the effects of annealing temperatures (TA) on a Pd (5 nm)/CoFeB (10 nm)/Pd (3 nm)/Ta (10 nm) multilayer structure. The as-deposited sample showed an amorphous state…
Impact of Annealing on Perpendicular Magnetic Anisotropy in W/MgAl2O4/CoFeMnSi/W/CoFeMnSi/MgAl2O4/W. Double Storage Layers for Upcoming MTJs
L. Saravanan, Nanhe Kumar Gupta, Vireshwar Mishra +2
In this study, we achieved the improvement of uniaxial perpendicular magnetic anisotropy (PMA) in the W/MgAl2O4/CoFeMnSi/W/CoFeMnSi/MgAl2O4/W heterostructure by manipulating the an…
