Experimental Verification of Van Vleck Nature of Long-Range Ferromagnetic Order in Vanadium-Doped Three-Dimensional Topological Insulator SbTe
Mingda Li, Cui-Zu Chang, Lijun Wu +6
We demonstrate by high resolution low temperature electron energy loss spectroscopy (EELS) measurements that the long range ferromagnetic (FM) order in vanadium (V)-doped topologic…
Polar State in Freestanding Strontium Titanate Nanoparticles
Trevor A. Tyson, Tian Yu, Mark Croft +6
Monodispersed strontium titanate nanoparticles were prepared and studied in detail. It is found that ~10 nm as-prepared stoichiometric nanoparticles are in a polar structural state…
Paramagnetic to ferromagnetic phase transition in lightly Fe-doped CrB
Leslie M. Schoop, Max Hirschberger, Jing Tao +3
CrB displays temperature independent paramagnetism. We induce ferromagnetism by replacing less than of the Cr atoms by Fe. By the lowest Fe doping level made, Curie-Wei…
Titanic Magnetoresistance in WTe2
Mazhar N. Ali, Jun Xiong, Steven Flynn +6
Magnetoresistance is the change of a material's electrical resistance in response to an applied magnetic field. In addition to its intrinsic scientific interest, it is a technologi…
Unveiling the microscopic origin of the electronic smectic-nematic phase transition in La1/3Ca2/3MnO3
Jing Tao, Kai Sun, Weiguo Yin +3
Electronic-liquid-crystal phases, in which part of the spatial symmetries are broken spontaneously, are considered to play a vital role in interpreting the structure-property relat…
Ferromagnetism and Spin-dependent Transport in n-type Mn-Bi2Te3 Thin Films
Joon Sue Lee, Anthony Richardella, David W. Rench +5
We describe a detailed study of the structural, magnetic, and magneto-transport properties of single-crystal, n-type, Mn-doped Bi2Te3 thin films grown by molecular beam epitaxy. Wi…
