A surprising “planar” thermal Hall effect, whereby the field is parallel to current, has recently been observed in a few magnetic insulators; this effect attributed exotic excitations such as Majorana fermions or chiral magnons. Here, we investigate possibility of planar three different cuprate materials, which conventional conductivity <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"><a:msub><a:mi>κ</a:mi><a:mi>xy</a:mi></a:msub></a:math> (with an out-of-plane...
A surprising "planar" thermal Hall effect, whereby the field is parallel to current, has recently been observed in a few magnetic insulators, and this attributed exotic excitations such as Majorana fermions or chiral magnons. Here we investigate possibility of planar effect three different cuprate materials, which conventional conductivity $\kappa_{\rm {xy}}$ (with an out-of-plane perpendicular current) dominated by either electrons phonons. Our measurements show that from cuprates zero,...
We report thermopower measurements under hydrostatic pressure on the cuprate superconductor La1.6−xNd0.4SrxCuO4 (Nd-LSCO), at low temperature in normal state accessed by suppressing superconductivity with a magnetic field up to H=31T. Using an ac measurement technique suitable for high and field, we track evolution of Seebeck coefficient S. At ambient temperature, S/T Nd-LSCO was recently found suddenly increase below pseudogap critical doping p★=0.23, consistent drop carrier density n from...
