Inverse Lieb Materials: Altermagnetism and More
Po-Hao Chang, Igor I. Mazin, Kirill D. Belashchenko
The Lieb lattice, originally proposed for cuprate superconductors, has gained new attention in the emerging field of altermagnetism as a minimal analytical model for the latter. Wh…
Doping-induced Spin Reorientation in Kagome Magnet TmMn6Sn6
Mohamed El Gazzah, Po-Hao Chang, Y. Lee +7
The kagome-lattice compounds RMn6Sn6 (R is a rare earth element), where the Mn atoms form a kagome net in the basal plane, are currently attracting a great deal of attention as the…
Three-dimensional nature of anomalous Hall conductivity in YMn6Sn6-xGax, x ~ 0.55
Hari Bhandari, Zhenhua Ning, Po-Hao Chang +8
The unique connectivity of kagome lattices gives rise to topological properties, such as flat bands and Dirac cones. When combined with ferromagnetism and a chemical potential near…
The mysterious magnetic ground state of Ba14MnBi11 is likely altermagnetic
Po-Hao Chang, Igor I. Mazin
Mn-based transition metal Zintl compounds in the 14-1-11 phase are known to host complex atomic and magnetic structures owing to their intricate crystal structure. Among them, Ba14…
Exploring Metamagnetism in Triangular Ising Networks: Insights from Further-Neighbor Interactions with a Case Study on ErGa2
Po-Hao Chang, Igor I. Mazin
The classical Ising model on the triangular lattice (we will call it I-3 model below), while simple in the nearest-neighbors (NN) only approximation, becomes increasingly richer an…
Voltage-controlled magnetic anisotropy in antiferromagnetic MgO-capped MnPt films
P. -H. Chang, W. Fang, T. Ozaki +1
The magnetic anisotropy in MgO-capped MnPt films and its voltage control are studied using first-principles calculations. Sharp variation of the magnetic anisotropy with film thick…
Origin of spin reorientation transitions in antiferromagnetic MnPt-based alloys
P. -H. Chang, I. A. Zhuravlev, K. D. Belashchenko
Antiferromagnetic MnPt exhibits a spin reorientation transition (SRT) as a function of temperature, and off-stoichiometric Mn-Pt alloys also display SRTs as a function of concentra…
