Emergent Ferromagnetism in CaRuo3/CaMnO3 (111)-Oriented Superlattices

Author(s)
Margaret Kane, Churna Bhandari, Megan Holtz, Purnima Balakrishnan, Alexander Grutter, Michael R. Fitzsimmons, Chao-Yao Yang, Sashi Satpathy, Durga Paudyal, Yuri Suzuki
The boundary between CaRuO3 and CaMnO3 is an ideal test bed for emergent magnetic ground states stabilized through interfacial electron interactions. In this

Practical realisation of the kelvin by Johnson noise thermometry

Author(s)
Horst Rogalla, D Rod White, Jifeng Qu, Samuel P. Benz, Christof Gaiser, Weston L. Tew, Nathan Flowers-Jacobs, Kevin J. Coakley, Alessio Polarollo, Chiharu Urano
Johnson noise thermometry (JNT) is a purely electronic method of thermodynamic thermometry. In primary JNT, the temperature is inferred from a comparison of the
