Bulk transport paths through defects in floating zone and Al flux grown SmB
Yun Suk Eo, Alexa Rakoski, Shriya Sinha +16
We investigate the roles of disorder on low-temperature transport in SmB crystals grown by both the Al flux and floating zone methods. We used the inverted resistance method wi…
Bulk and surface properties of SmB6
Priscila F. S. Rosa, Zachary Fisk
Samarium hexaboride crystallizes in a simple cubic structure (space group #221, Pm-3m), but its properties are far from being straightforward. Initially classified as a Kondo insul…
Colossal magnetoresistance in a nonsymmorphic antiferromagnetic insulator
P. F. S. Rosa, Yuanfeng Xu, S. K. Kushwaha +14
Here we investigate antiferromagnetic EuInSb, a nonsymmorphic Zintl phase. Our electrical transport data show that EuInSb is remarkably insulati…
Hall coefficient diagnostics of surface state in pressurized SmB6
Yazhou Zhou, Priscila F. S. Rosa, Jing Guo +9
In this study, we report the first results of the high-pressure Hall coefficient (RH) measurements in the putative topological Kondo insulator SmB6 up to 37 GPa. Below 10 GPa, our…
Magnetic field-tuned quantum criticality in a Kondo insulator
Satya K. Kushwaha, Mun K. Chan, Joonbum Park +6
Kondo insulators are predicted to undergo an insulator-to-metal transition under applied magnetic field, yet the extremely high fields required to date have prohibited a comprehens…
Raman spectroscopy of -electron metals: an example of CeB
Mai Ye, H. -H. Kung, Priscila F. S. Rosa +3
We performed an optical spectroscopy study of electronic and magnetic excitations for a rare-earth system with a single electron quasi-localized in the f-shell on an ion at high-sy…
