Investigating nucleation-driven phase transitions in neopentyl molecular crystals using infrared thermography and polarised light microscopy
Frederic Rendell-Bhatti, Vinzent G. Hana, Csongor Joba +2
Sustainable solid-state refrigerants based on barocaloric materials are often limited by thermal hysteresis associated with supercooling effects. Here, we present imaging methods t…
Enhanced reversible barocaloric effect at low pressure in neopentyl plastic crystal solid solutions
Frederic Rendell-Bhatti, Melony Dilshad, Celine Beck +9
The discovery of colossal barocaloric effects in neopentyl glycol (NPG) makes plastic crystals promising candidates for solid-state refrigerants with lower environmental impact tha…
Multi-site exchange enhanced barocaloric response in MnNiN
David Boldrin, Eduardo Mendive-Tapia, Jan Zemen +9
We have studied the barocaloric effect (BCE) in the geometrically frustrated antiferromagnet MnNiN across the Néel transition temperature. Experimentally we find a larger ba…
The Impact of Local Strain Fields in Non-Collinear Antiferromagnetic Films
Freya Johnson, Frederic Rendell-Bhatti, Bryan D. Esser +5
Antiferromagnets hosting structural or magnetic order that breaks time reversal symmetry are of increasing interest for 'beyond von Neumann computing' applications because the topo…
Spin dynamics in the S =1/2 kagome compound vesignieite, Cu3Ba(VO5H)2
Ross H Colman, Fabrice Bert, David Boldrin +5
We report the study of high quality samples of the frustrated S = 1/2 kagome antiferromagnet vesignieite, Cu3Ba(VO5H)2. Neutron powder diffraction measurements evidence the high qu…
Confinement in metal-organic frameworks as a route to harnessing liquid barocalorics in the solid-state
Ming Zeng, Frederic Rendell-Bhatti, Eamonn T. Connolly +5
Barocaloric (BC) effects at liquid-vapor transitions in hydrofluorocarbons drive most commercial technologies used for heating and cooling in the heating, ventilation and air-condi…
Direct observation of thermal hysteresis in the molecular dynamics of barocaloric neopentyl glycol
Frederic Rendell-Bhatti, Markus Appel, Connor S. Inglis +6
Barocalorics (BCs) are emerging as promising alternatives to vapour-phase refrigerants, which are problematic as they exacerbate climate change when they inevitably leak into the a…
The anomalous Hall effect in non-collinear antiferromagnetic MnNiN thin films
David Boldrin, Ilias Samathrakis, Jan Zemen +7
We have studied the anomalous Hall effect (AHE) in strained thin films of the frustrated antiferromagnet MnNiN. The AHE does not follow the conventional relationships with ma…
