Firsrt and second attempt: standard minimizations without pressure.
 The second one starts from the first optimized basis set.

-----------------------------------------------------------
Third attempt: Increase the tolerance factors for La 5d and Al 2p

Starting from the optimized basis set number 2,
we increased the tolerance factors for La 5d and Al 3p orbitals,
in order to avoid the WARNING that appears in the output of
Siesta related with the small SplitNorm of these atomic orbitals.

One of the parameters of the optimized basis set number 2 was
modified to comply with the new tolerance: 
the cutoff radius of the second-zeta of the Al 3p.

-----------------------------------------------------------

Fourth attempt: Introduce a pressure of 0.03 GPa

Starting from the optimized basis set number 3, 
we perform an optimization of the enthalpy with a 
pressure of 0.03 GPa. 

The goal is to reduce the range of the atomic orbitals
(some of them where too long).

-----------------------------------------------------------

Fifth attempt: Introduce a pressure of 0.03 GPa,
               and avoid some parameters to be in the border
               of the tolerance.

In the optimized bsais set number 4, two parameters
(the charge of La and the separation between the first and second-zeta
Al 3p orbitals) were in the limits of maximum value and the tolerance
respectively.
Besides, for the Al 3p orbitals, the WARNING of a small SplitNorm remained.

Starting from the optimized basis set number 4, 
we perform an optimization of the enthalpy with a 
pressure of 0.03 GPa. 
The Initial basis set was modified, with the charge of La far away
from the maximum value, and increasing the tolerance of Al 3p up to 2.5 bohrs.
