  In our mini-review, we address manifestations of $T/B$ scaling behavior of
heavy-fermion (HF) compounds, where $T$ and $B$ are respectively temperature
and magnetic field. Using experimental data and the fermion condensation
theory, we show that this scaling behavior is typical of HF compounds including
HF metals, quasicrystals, and quantum spin liquids. We demonstrate that such
scaling behavior holds down to the lowest temperature and field values, so that
$T/B$ varies in a wide range, provided the HF compound is located near the
topological fermion condensation quantum phase transition (FCQPT). Due to the
topological properties of FCQPT, the effective mass $M^*$ exhibits a universal
behavior, and diverges as $T$ goes to zero. Such a behavior of $M^*$ has
important technological applications. We also explain how to extract the
universal scaling behavior from experimental data collected on different
heavy-fermion compounds. As an example, we consider the HF metal $\rm
YbCo_2Ge_4$, and show that its scaling behavior is violated at low
temperatures. Our results obtained show good agreement with experimental facts.
