摘要翻译：
用磁转矩测量方法研究了团簇超导体ZrB12中的de Haas-Van Alphen效应(dHvA),在28T以下的磁场中，在0.35K以下的温度下，探测到了由颈截面和费米面的“立方盒”轨道引起的dHvA振荡。我们测量了FS颈部的回旋有效质量为0.5M_0。在广义梯度近似下，利用全位势线性Muffin-Tin轨道(LMTO)方法计算了dHvA频率和回旋有效质量。将dHvA频率的角度依赖性与能带结构计算结果进行比较，表明与理论模型基本一致，但其中一个截面不能确定。

英文摘要：
The de Haas - van Alphen (dHvA) effect in the cluster superconductor ZrB12 was studied by magnetic torque measurements in magnetic fields up to 28 T at temperatures down to 0.35 K. The dHvA oscillations due to orbits from the Neck sections and "Cubic Box" of the Fermi surface were detected. We measured cyclotron effective masses of 0.5m_0 for Neck section of the FS. The dHvA frequencies as well as the cyclotron effective masses were calculated using the full potential Linear Muffin-Tin Orbital (LMTO) method within the Generalized Gradient Approximation. Comparison of the angular dependence of the dHvA frequencies with the band-structure calculations implies overall agreement with theoretical model, while one section could not be definitely identified.
