Summary: | Recent studies have dealt with the electronic and magnetic ground state
properties of the tetraboride material MnB$_4$. So far, however, the ground
state properties could not be established unambiguously. Therefore, here we
present an experimental study on single-crystalline MnB$_4$ by means of
resistivity and magnetization measurements. For this, we have developed a
sample holder that allows four-point ac resistivity measurements on these very
small ($\sim$\,100\,$\mu$m) samples. With our data we establish that the
electronic ground state of MnB$_4$ is intrinsically that of a pseudo-gap
system, in agreement with recent band structure calculations. Furthermore, we
demonstrate that the material does neither show magnetic order nor a behavior
arising from the vicinity to a magnetically ordered state, this way disproving
previous claims. |
