The Dipole-Octupole Quantum Spin Ice Candidate Ce2Zr2O7

Autor: Smith, Evan M.

This thesis focuses on the cerium-based, insulating pyrochlore magnet Ce2Zr2O7. Of particular popularity in the condensed matter community are insulating rare-earth pyrochlores with chemical formula R2B2O7, with magnetism based on trivalent rare-eart

Magnetic Field Tuning of Parallel Spin Stripe Order and Fluctuations near the Pseudogap Quantum Critical Point in La$_{1.36}$Nd$_{0.4}$Sr$_{0.24}$CuO$_4$

Autor: Ma, Qianli, Smith, Evan M., Cronkwright, Zachary W., Dragomir, Mirela, Mitchell, Gabrielle, Winn, Barry W., Williams, Travis J., Gaulin, Bruce D.

A quantum critical point in the single layer, hole-doped cuprate system La$_{1.6-x}$Nd$_{0.4}$Sr$_x$CuO$_4$ (Nd-LSCO), near $x$ = 0.23 has been proposed as an organizing principle for understanding high temperature superconductivity. Our earlier neut

Chiral Phase Change Nanomaterials

Autor: Burrow, Joshua A., Alam, Md Shah, Smith, Evan M., Yahiaoui, Riad, Laing, Ryan, Shah, Piyush J., Searles, Thomas A., Vangala, Shivashankar, Hendrickson, Joshua R., Sarangan, Andrew, Agha, Imad

Chiral nanostructures offer the ability to respond to the vector nature of a light beam at the nanoscale. While naturally chiral materials offer a path towards scalability, engineered structures offer a path to wavelength tunability through geometric

Dynamic Parallel Spin Stripes from the 1/8 anomaly to the End of Superconductivity in La$_{1.6-x}$Nd$_{0.4}$Sr$_x$CuO$_4$

Autor: Ma, Qianli, Smith, Evan M., Cronkwright, Zachary W., Dragomir, Mirela, Mitchell, Gabrielle, Kolesnikov, Alexander I., Stone, Matthew B., Gaulin, Bruce D.

We have carried out new neutron spectroscopic measurements on single crystals of La$_{1.6-x}$Nd$_{0.4}$Sr$_x$CuO$_4$ from 0.12 to 0.26 using time-of-flight techniques. These measurements allow us to follow the evolution of parallel spin stripe fluctu

Parallel Spin Stripes and Their Coexistance with Superconducting Ground States at Optimal and High Doping in La$_{1.6-x}$Nd$_{0.4}$Sr$_x$CuO$_4$

Autor: Ma, Qianli, Rule, Kirrily C., Cronkwright, Zachary W., Dragomir, Mirela, Mitchell, Gabrielle, Smith, Evan M., Chi, Songxue, Kolesnikov, Alexander I., Stone, Matthew B., Gaulin, Bruce D.

Publikováno v: Phys. Rev. Research 3, 023151 (2021)

Quasi-two dimensional quantum magnetism is clearly highly correlated with superconducting ground states in cuprate-based High T$_c$ superconductivity. Three dimensional, commensurate long range magnetic order in La$_2$CuO$_4$ quickly evolves to quasi
