Perpendicular Magnetic Anisotropy in Conducting NiCo2O4 Films from Spin-Lattice Coupling
Corbyn Mellinger, Jace Waybright, Xiaozhe Zhang +2
High perpendicular magnetic anisotropy (PMA), a property needed for nanoscale spintronic applications, is rare in oxide conductors. We report the observation of a PMA up to 0.23 MJ…
Absence of Metallic Behavior in Epitaxial NiCo2O4 Thin Films: Role of Microstructural Disorder
Congmian Zhen, XiaoZhe Zhang, Wengang Wei +6
Despite the low resistivity (~ 1 mohm cm), the metallic electrical transport has not been commonly observed in the inverse spinel NiCo2O4, except in certain epitaxial thin films. P…
Electronic structure and direct observation of ferrimagnetism in multiferroic hexagonal YbFeO3
Shi Cao, Kishan Sinha, Xin Zhang +12
The magnetic interaction between rare-earth and Fe ions in hexagonal rare-earth ferrites (h-REFeO3), may amplify the weak ferromagnetic moment on Fe, making these materials more ap…
Effect of interface on epitaxy and magnetism in h-RFeO3/Fe3O4/Al2O3 films (R=Lu, Yb)
Xiaozhe Zhang, Yuewei Yin, Sen Yang +2
We have carried out the growth of h-RFeO3 (001) (R=Lu, Yb) thin films on Fe3O4 (111)/Al2O3 (001) substrates, and studied the effect of the h-RFeO3 (001)/Fe3O4 (111) interfaces on t…
Effects of biaxial strain on the improper multiferroicity in h-LuFeO3 films
Kishan Sinha, Yubo Zhang, Xuanyuan Jiang +11
Elastic strain is potentially an important approach in tuning the properties of the improperly multiferroic hexagonal ferrites, the details of which have however been elusive due t…
Room Temperature Ferroelectricity in Continuous Croconic Acid Thin Films
Xuanyuan Jiang, Haidong Lu, Yuewei Yin +10
Ferroelectricity at room temperature has been demonstrated in nanometer-thin quasi 2D croconic acid thin films, by the polarization hysteresis loop measurements in macroscopic capa…
Phase separation in LuFeO3 films
Shi Cao, Xiaozhe Zhang, Kishan Sinha +4
The structural transition at about 1000 °C, from the hexagonal to the orthorhombic phase of LuFeO3, has been investigated in thin films of LuFeO3. Separation of the two structural…
On the Structural Origin of the Single-ion Magnetic Anisotropy in LuFeO3
Shi Cao, Xiaozhe Zhang, Tula R. Paudel +12
Electronic structures for the conduction bands of both hexagonal and orthorhombic LuFeO3 thin films have been measured using x-ray absorption spectroscopy at oxygen K (O K) edge. D…
Kinetics and Intermediate Phases in Epitaxial Growth of Fe3O4 Films from Deposition and Thermal Reduction
Xiaozhe Zhang, Sen Yang, Zhimao Yang +1
We have studied the growth of Fe3O4 (111) epitaxial films on Al2O3 (001) substrates using a pulsed laser deposition / thermal reduction cycle using an α-Fe2O3 target. While direct…
