An antiferromagnetic transition was found at T$_M$ = 11 K. The antiferromagnetic order can be tuned by an applied magnetic field to access a first-order spin flop transition ... More
Counting isolated points outside the image of a polynomial mapSep 18 2019Let $f=(f_1,f_2):\C^2\rightarrow\C^2$ be a non-proper polynomial map, and let $d(f)$ denote the maximum degree of $f_1$, and $f_2$. We show that for a large family of such maps, the number of isolated points in $\C^2\setminus f(\C^2)$ is bounded from ... More
