Dipolar Spin Ice Regime Proximate to an All-In-All-Out Néel Ground State in the Dipolar-Octupolar Pyrochlore Ce2Sn2O7

The dipolar-octupolar (DO) pyrochlores, $R_2{M}_2{\mathrm{O}}_7$ ( $R=\mathrm{Ce},\mathrm{Sm},\mathrm{Nd}$ ), are key players in the search for realizable novel quantum spin liquid (QSL) states as a large parameter space within the DO pyrochlore phase diagram is theorized to host QSL states of both dipolar and octupolar nature. New single crystals and powders of ${\mathrm{Ce}}_2{\mathrm{Sn}}_2{\mathrm{O}}_7$ , synthesized by hydrothermal techniques, present an opportunity for a new characterization of the exchange parameters in ${\mathrm{Ce}}_2{\mathrm{Sn}}_2{\mathrm{O}}_7$ using the …
