Coexisting Paramagnetic Spins and Long-Range Magnetic Order in Ba(RuIr)O
Farhan Islam, Jiasen Guo, Wei Tian +6
We investigate the effect of dilute Ir substitution on the magnetism of the trimer-based ruthenate BaRuO using neutron diffraction, magnetic susceptibility measureme…
Spiral Spin Liquid State in the Corrugated Honeycomb Lattice of CaMnP
Farhan Islam, Nikita D. Andriushin, Thaís V. Trevisan +9
CaMnP exemplifies the realization of a frustrated -- Heisenberg model of a corrugated honeycomb magnetic lattice. Previous studies show that below the Néel t…
Coexistence of Ferromagnetism and Antiferromagnetic Dimers in Topological Insulators
Farhan Islam, Deborah Schlagel, Yongbin Lee +6
The addition of magnetic impurities in topological insulators can drive ferromagnetic order that leads to novel quantum anomalous Hall transport well below the Curie temperature. T…
Anisotropic magnetism and electronic structure of trigonal EuAlGe single crystals
Santanu Pakhira, Asish K. Kundu, Farhan Islam +10
The magnetic and electronic properties of the layered Zintl-phase compound EuAlGe crystallizing in the trigonal CaAlSi-type structure are reported. Our neutron-diff…
Role of Magnetic Defects and Defect-engineering of Magnetic Topological Insulators
Farhan Islam, Yongbin Lee, Daniel M. Pajerowski +5
Magnetic defects play an important, but poorly understood, role in magnetic topological insulators (TIs). For example, topological surface transport and bulk magnetic properties ar…
Frustrated Magnetic Cycloidal Structure and Emergent Potts Nematicity in CaMnP
Farhan Islam, Thaís V. Trevisan, Thomas Heitmann +6
We report neutron-diffraction results on single-crystal CaMnP containing corrugated Mn honeycomb layers and determine its ground-state magnetic structure. The diffraction p…
A-type antiferromagnetic order in semiconducting EuMgSb single crystals
Santanu Pakhira, Farhan Islam, Evan O'Leary +6
Eu-based Zintl-phase materials EuAPn (A = Mg, In, Cd, Zn; Pn = Bi, Sb, As, P) have generated significant recent interest owing to the complex interplay of magnetism and ban…
