All these studies universally show that the resistivity $\\rho_{a}$ across the long orthorhombic axis $a_{O}$ - along which the spins couple antiferromagnetically below the magnetic transition temperature - is smaller than the resistivity $\\rho_{b}$ of the short orthorhombic axis $b_{O}$, i. e. $\\rho_{a}<\\rho_{b}$.
