Formation of Core-Shell Precipitates in off-stochiometric Ni-Mn-Sn Heusler alloys probed through the induced Sn-moment
Benedikt Eggert, Aslı Çakır, Damian Günzing +7
The Shell-ferromagnetic effect originates from the segregation process in off-stochiometric Ni-Mn-based Heusler. In this work, we investigate the precipitation process of L2-or…
Complete crystallographic, spin-electronic and magnetic structure of (Co0.2Cr0.2Fe0.2Mn0.2Ni0.2)3O4: Unraveling the suppression of entropy in high entropy oxides
Abhishek Sarkar, Benedikt Eggert, Ralf Witte +12
High entropy oxides (HEOs) are a rapidly emerging class of functional materials consisting of multiple principal cations. The original paradigm of HEOs assumes cationic occupations…
Role of intermediate 4 states in tuning the band structure of high entropy oxides
Abhishek Sarkar, Benedikt Eggert, Leonardo Velasco +8
High entropy oxides (HEOs) are single phase solid solutions consisting of 5 or more cations in approximately equiatomic proportions. In this study, we show reversible control of op…
Magnetic properties of rare earth and transition metal based perovskite type high entropy oxides
Ralf Witte, Abhishek Sarkar, Leonardo Velasco +7
High entropy oxides (HEO) are a recently introduced class of oxide materials, which are characterized by a large number of elements (i.e. five or more) sharing one lattice site whi…
Epitaxial strain adaption in chemically disordered FeRh thin films
Ralf Witte, Robert Kruk, Di Wang +5
Strain and strain adaption mechanisms in modern functional materials are of crucial importance for their performance. Understanding these mechanisms will advance innovative approac…
High entropy oxides: An emerging prospect for magnetic rare earth - transition metal perovskites
Ralf Witte, Abhishek Sarkar, Robert Kruk +4
It has been shown that oxide ceramics containing multiple transition and/or rare-earth elements in equimolar ratios have a strong tendency to crystallize in simple single phase str…
Tailoring Magnetic Frustration in Strained Epitaxial FeRh Films
Ralf Witte, Robert Kruk, Markus E. Gruner +8
We report on a strain-induced martensitic transformation, accompanied by a suppression of magnetic order in epitaxial films of chemically disordered FeRh. X-ray diffraction, transm…
Magnetic Phase Transition and Relaxation Effects in LiFePO4
Y. Sundarayya, C. Bansal, C. S. Sunandana +3
We report the observation of para - antiferromagnetic transition at ~ 50 K in lithium iron phosphate, LiFePO4 through DC magnetization and Mössbauer spectroscopy. The Ferrous ion F…
