We introduce four new molecules -- YbRb, YbCs, YbSr$^+$, and YbBa$^+$ -- that may prove fruitful in experimental searches for the electric dipole moment (EDM) of the electron. These molecules can, in principle, be prepared at extremely low…

We propose using matrix-isolated paramagnetic diatomic molecules to search for the electric dipole moment of electron (eEDM). As was suggested by Shapiro in 1968, the eEDM leads to a magnetization of a sample in the external electric field.…
